StacoVT Variable Transformer, Single, 240V 50/60 Hz

Staco Energy Products' full range of variable transformers offer the exceptional versatility and reliability required for so many of today's voltage control applications in both industrial and laboratory environments. Unlike a standard fixed ratio transformer, a Staco variable transformer is designed to provide variable output voltage that can be adjusted from 0 to 117% of the unit's input voltage. Staco Energy Products Co. offers a wide range of standard models including the following: Panel mount, single phase (fixed and adjustable shaft) Enclosed cord and plug Metered Fully enclosed Ganged Isolated Isolated portable cord and plug models "Quick-Step" motorized Motor driven Cased A basic Staco variable transformer consists of a copper winding on a toroidal core of laminated, grain-oriented, silicon steel. A carbon brush, connected to an output terminal, is rotated over the length of a precision-ground, precious metal-plated, commutator track to tap off voltage at any turn from zero volts to the maximum output voltage of the winding.
